PUNCHING AND EYELETING MACHINE.

SPECIFICATION forming part of Letters Patent No. 557,738, dated April 7, 1896.

Application filed December 1, 1892- Serial No. 453,708- (No model.) Patented in France March 28, 1890, No. 204,660, in

Belgium March 28, 1890,11'0. 90,007, and in England April 9,1890,N0.5,397.

To all whom it may concern.-

Be it known that I, CHARLES WHITFIELD, of Kettering, in the county of Northampton, England, have invented certain new and usef ul Improvements in Punching and Eyeletin g Machines, (for which I have obtained patents in Great Britain, No. 5,397, dated April 9, 1800; in France, No. 204;, 660, dated March 28, 1800, and in Belgium, No. 90,007, dated March 28, 1800,) of which the following is a specification.

This invention relates to combined punching and eyeleting machines; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of the machine, partly in section. Fig. 2 is a front view of the machine. Fig. 3 is a side view of the machine, showing the parts in a position to close the eyelet. Fig. 4 is a detail sectional view of the punch and die, drawn to a larger scale.

A bracket (Z is secured to any convenient support, and is provided with a guide cl for the plunger 71 The upper die on is secured to the upper part of the bracket. The punch 5 slides in the hollow plunger h and passes through the lower eyeleting-die at the top of the plunger 72 A feeder a for the eyelets is provided and is carried by the bell-crank lever c, pivoted on the pin 0, projecting from the bracket d. A chute Z) is connected to the receptacle of the feeder and projects between the punch and the upper die. An oscillatory plate 6 is pivoted on the pin 6, projecting from the lower part of the bracket d. This plate 6 is provided with four pins 2, 3, a, and 5, placed at difierent distances from the pivot-pin e.

As a convenient means for operating the machine a treadle 7c is provided and is connected to the pin 2 by the rod j, and a spring 6 is used to give the parts their return motion. This spring is shown broken in the drawings to show the parts beyond it. Any other approved mechanism may be used for oscillating the plate 6 if desired.

The lower arm 7 of the bell-crank lever c is provided with a slot 8, and 9 are links pivoted to the pin 3. These links are provided with a pin 10 at their upper end, which pin is adapted to slide in the said slot 8.

A link g is pivoted to the lower end of the punch 2' and t0 the pin 5, and f are links which are pivoted to the pin 4 and to the lower end of the plunger 72-. The pin is placed at a greater distance from the pivotpin 6 than the pin 4, so that the punch may have the longer stroke.

The parts are normally held in the position shown in Fig. 1 by the spring 6.

YVhen the treadle is depressed, the lever c at first remains stationary as the pin slides down the slot 8. The punch and the plunger rise together, the punch being pushed up at a greater speed than the plunger. The top of the punch has a shoulder which supports the eyelet which the punch picks up from the bottom of the chute b. As soon as the punch has picked up the eyelet the chute b is moved back out of the way by the lever c, which is now turned on its pivot. The continued upward movement of the punch performs the punching operation, and the speed of the plunger increases so that the eyeleting operation is performed when the punch reaches its highest position and the parts are in the position shown in Fig. 3.

What I claim is- The combination, with the supportingbracket, of the bell-crank lever c pivoted to the said bracket and provided with the slot 8, a self-feeder for the eyelets secured to the said lever, the stationary die m, the punch 2 the tubular die 0, the oscillatory plate 6, and separate links pivotally connecting the said bell-crank lever, the punch and the tubular die with the said plate, substantially as and for the purpose set forth.

In testimony whereof I affix my signature to the foregoing specification.
